The ProAudio allows you to set minimum and maximum volume limits on a per-zone basis using the Config Tool. This prevents users from setting volume below the room noise floor or above a safe level for the connected speakers and amplifiers.
How to Set Min and Max Volume
1
Open the Config Tool and connect to your ProAudio unit.
2
Click the Stereo Zones tab.
3
Locate the zone you want to configure. Click the volume bars icon (second icon from the left in the row of four icons at the top of the zone) to expand the Levels panel for that zone.
4
Set the Min Volume field to the lowest volume level you want to allow for this zone in dB. The default is -60dB.
5
Set the Max Volume field to the highest volume level you want to allow for this zone in dB. The default is 12dB.
6
Repeat for each zone that needs limits applied.
7
In the sidebar, tick Zone audio parameters and click Save Selected to save the settings permanently.
The Other Levels Settings
The Levels panel also contains two additional settings:
| Setting | What it does |
|---|---|
| Mute Level | Sets the internal level value used when the zone is muted. Default is 248. This should not normally need to be changed. |
| Mute Level Mode | Controls how the volume transitions when muting. Default is Sloped, which fades the volume out gradually rather than cutting abruptly. |
Guidance on Setting Min and Max Values
- Min Volume: Set this just above the noise floor of the amplifier and speakers in that zone. If the minimum is set too low, the volume range at the bottom end will feel unresponsive — the user will turn the volume up but hear nothing until it clears the noise floor. A starting point of -60dB to -40dB works for most installations.
- Max Volume: Set this to a level that the connected amplifier and speakers can handle cleanly without distortion. If you hear distortion at the current maximum, reduce this value. The default of 12dB is a safe starting point for most installations.
- Keeping the range sensible: The tighter the range between min and max, the more predictable the volume control feels to the end user. A very wide range (e.g. -80dB to +20dB) means most of the useful volume range is compressed into a small portion of the control travel.
